AMSA in a media release Sunday, however, the object was not sighted during yesterday's search.
"Yesterday, China provided a satellite image to Australia, possibly showing a 22.5 metre floating object in the southern Indian Ocean. AMSA plotted the position and it fell within yesterday's search area but the object was not sighted," the release added.
AMSA said it used the information in the development of the search area, taking drift modelling into account.
Today's search has been split into two areas within the same proximity covering 59,000 square kilometres, about 2,500 kilometres south west of Perth, and these areas have been determined by drift modelling, it added reiterating such an operation was very challenging.
The release further said, eight aircraft have been tasked by AMSA's Rescue Coordination Centre to undertake today's search activities.
"The civil aircraft are two Bombardier Global Express, a Gulfstream 5 and an Airbus 319. One civil aircraft departed Perth for the search area just after 9am. Three other civil aircraft departed for the search area between 11 am and midday," it added.
The release said, the United States Navy P8 Poseidon aircraft departed for the search area at about 11am.
"A Royal Australian Air Force (RAAF) P3 Orion aircraft departed RAAF Base Pearce about 11.45am. This aircraft will be followed by a second RAAF P3 Orion about 2pm," it added.
The release further said, a Royal New Zealand Air Force (RNZAF) P3 Orion is scheduled to depart for the search area at 4pm.
"HMAS Success is also conducting search activities today. A total of 20 State Emergency Service (SES) volunteers from Western Australia have been tasked as air observers on the civil jets today.
"Each civil aircraft will have five SES air observers on board as well as an Aerorescue Aviation Mission Coordinator. Aerorescue is AMSA's contracted provider of dedicated search and rescue services from locations across Australia," it added.
Two Chinese military Ilyushin IL-76 aircraft have arrived at the RAAF Base Pearce. AMSA has been advised that these aircraft will be ready for tasking tomorrow, the release said.
